The rocky cliffs of Yosemite, the wooded hills of Shenandoah—each of the United States' national parks is iconic. And as we celebrate the hundredth anniversary of the National Park Service on Thursday, we want to know how well you can identify these icons of nature.
President Woodrow Wilson signed the act that created the NPS on August 25, 1916, though Yellowstone National Park, the first national park, was created in 1872. The NPS now covers more than 84 million acres across the U.S., at sites as diverse as national monuments, Civil War battlefields, and historic sites.
There's a big range in size among NPS sites, too: The biggest is Wrangell-St. Elias National Park and Preserve in Alaska, at 13.2 million acres, while the smallest is Thaddeus Kosciuszko National Memorial in Pennsylvania, at 0.02 acre. These sites attract more than 300 million visitors every year, and the NPS commands a budget of billions ($2.98 billion in the 2014 fiscal year and $3.65 billion in the 2015 fiscal year) to administer and maintain its lands.
